They did tell us about side effects that can occur during treatment. They did mention that some side effects continue well past treatment. But when he had no side effects during treatment we thought we were in the clear. Interestingly enough, before the bleeding became visible my husband became anemic. He had several scopes and no internal bleeding was found. So we called the cancer clinic even though he had been discharged from their care. They said the anemia was not likely due to the radiation considering that 2 years had passed. But shortly after there was active bleeding and we ended up at emergency. The surgeon on call found the bleeding rectal ulcer and diagnosed as radiation induced proctitis. We did 8 weeks of twice daily sucralfate enemas. The bleeding has resolved but the bowel urgency and occasional incontinence has remained. The doctor's solution is metamucil.
